$

Explanation:

Step1: Calculate the cost of memory cards

The cost of one memory card is $8.99. Richard buys 2 memory cards. So the cost of memory cards is \(2\times8.99 = 17.98\)

Step2: Calculate the cost of batteries

The cost of one package of batteries is $7.47. Richard buys 3 packages. So the cost of batteries is \(3\times7.47=22.41\)

Step3: Calculate the cost of the cell - phone case and the wireless headset

The cost of the cell - phone case is $2.99 and the cost of the wireless headset is $29.99. The sum of their costs is \(2.99 + 29.99=32.98\)

Step4: Calculate the total cost

Add the costs from Step1, Step2 and Step3 together. The total cost \(C=17.98+22.41 + 32.98\)
